[Percutaneous transluminal radiofrequency renal denervation is a promising new therapeutic method for the treatment of primary resistant hypertension. The intervention decreases the systemic sympathetic over activation and thus arterial blood pressure. In the 1st Department of Medicine of the University of Szeged, 9 resistant hypertensive patients (2 male, 7 female; mean age: 55.0±4.0 years) had all the conditions were required for renal denervation at the time of interventions were performed. We measured the blood pressure together with the heart rate of the patients on the day preceding the intervention, right after the intervention, at discharge from hospital, then at months 6, 9 and 15. The mean blood pressure was 178/107±7/5 mmHg before the intervention. After denervation mean blood pressure decreased right after the intervention, at discharge from hospital, as well as at months 6, 9 and 15, respectively -15/-17 mmHg; -36/-16 mmHg; -19/-9 mmHg; -27/-21 mmHg and -15/- 16 mmHg. Besides decreasing of blood pressure, the antihypertensive drug therapy also decreased, however, it was not the primary aim of the intervention. No denervation- related intra- or perivascular complications were detected. The findings of our study proved the efficacy and safety of renal denervation in the treatment of primary resistant hypertension, of course with an appropriate patient selection. Our study was not relevant to determine whether this method is accompanied with a significant decrease of cardiovascular morbidity and mortality. Answers may come only based on randomized sham controlled studies with great case numbers.]

Patient with a spontaneously evolving carotid cavernous fistula in the emergency department

SZABÓ István, ZAG Levente, CSONTOS Amarilla, TAKÁCS F. Irma, SZIKORA István

Background - Approximately 2% of patients admitted to the emergency department present with headache, which is often associated with vomiting, ocular pain, and earache. In rare cases, the presence of an abnormal communication between a cavernous sinus and the carotid arterial system that creates a carotid cavernous fistula is the main cause of these symptoms. Case presentation - A 32-year-old woman presented at the emergency department with unilateral headache associated with earache on the same side, and pulsating tinnitus. On examination, we observed unusual appearance of our patient (small stature, unusually visible skin, lobeless ears). In the first 5 hours of our observation no neurological symptoms had been present, but after a severe vomiting, exophthalmos, subconjunctival suffusion and moderate ptosis developed. First, regarding the initial general symptoms, otorhinolaryngologist assessed the patient, and did not find any abnormality. Further, we ordered computed tomography and consulted a neurologist. Despite of the negative results we continued the observation because her symptoms did not improve. After appearance of neurological symp-toms, carotid cavernous fistula was suspected. Magnetic resonance imaging and ophthalmologist consultation verified the diagnosis. For therapy, she was transferred to interventional neuroradiology. Because of the unusual appearance and carotic cavernous fistula, we ordered genetic examination. This indicated the presence of Ehlers-Danlos syndrome type IV in the background. The first major manifestation of the syndrome was observed at our department. Conclusions - Carotid cavernous fistula is an uncommon diagnosis in the emergency department; however, the early recognition of symptoms and early treatment can prevent further consequences of this potentially severe condition.

[Hemodynamic approach of the treatment of hypertension. The possible role of impedance cardiography in the tailored antihypertensive therapy]

SIMONYI Gábor, ZSUZSA Pál

[It is important to achieve the blood pressure targets in the course of antihipertensive therapy. It will be beneficial to increase the proportion of patients on blood pressure target to avoid adverse cardiovascular consequences. In hypertension the main definition the elevation of blood pressure alone, but in hypertension are several abnormalities of cardiac output, systemic vascular resistance, stroke volume and arterial compliance too. Impedance cardiography is a simple highly accurate non-invasive device to assess hemodynamic parameters in hypertension. Hemodynamic assessment may help in the treatment of hypertension. Various authors report the improving rate of blood control rate using impedance cardiography which may decrease the risk of target organ damage.]

[Dissections of the supraaortic arteries]

CSEH Tamás, SZUKITS Sándor, SZAPÁRY László

[Dissection of the cervical and intracranial vasculature is a rare but important cause of ischaemic stroke especially in young adults. In the majority of cases it affects the extracranial vessels, mostly the internal carotid artery. It might be categorized as spontaneous or traumatic, causing diverse clinical symptoms. Dissection might lead to ipsilateral stroke mainly by artery-to-artery embolisation. Due to its relative rarity compared to the classic ischaemic stroke of the elderly, there are much less clinically relevant information for the clinician to rely on. Several large, randomised, multicentered, prospective studies and some smaller, retrospective analyses have been published recently concerning the genetic background, epidemiology, acute care and secondary prevention of supraaortic arterial dissection which helps the neurologist to provide evidence-based care for his patient. Our aim is to give a short, up-to-date overview of arterial dissections with two case reports.]

[The effect of anesthesia on cognitive functions]

BOCSKAI Tímea, KARÁDI Kázmér, BURIÁN András, KOVÁCS Norbert, BOGÁR Lajos, LUJBER László

[Aim of the study - General anesthetics, arterial hypotension and hypoxia developing during anesthesia may result in impaired memory and a decline in other abilities (such as attention, concentration, linguistic and writing abilities). Our aim was to detect changes in cognitive functions due to surgery and anesthesia with controlled arterial hypotension. Materials and methods - We studied combined and intravenous anesthesia detecting pre-and postoperative cognitive functions, intraoperative haemodynamic parameters, demographic data, other data of case history and surgical data. The Montreal Cognitive Assessment test was applied in the randomized, prospective study. The preoperative data served as basis for comparison. The second test was performed following surgery when patients were fully awake. Both groups included 30 patients. Results and conclusion - After both narcosis methods (postoperative second hour) cognitive functions were significantly deteriorated (p<0.05). Median MoCA before sevoflurane anesthesia was 24 points (interquartile range: 22-25), postoperative value was 20 (19-21) (p<0.05). Median MoCA before propofol anesthesia was 24 points (23-26), postoperative value was 20 (18-22) (p<0.01). Intraoperative arterial blood pressure, pulse rate and oxygen saturation values did not correlate with worsening of cognitive function (Pearson correlation coefficient values between -0.19 and 0.42). Execution is influenced by age (negative correlation) and education (positive correlation).]

[Neurological symptoms in a patient with treated multiple myeloma]

ZOMBORI Tamás, PIUKOVICS Klára

[INTRODUCTION - Meningeal infiltration by multiple myeloma is rare. Its incidence among cases of multiple myeloma is 1%. CASE REPORT - Multiple myeloma was diagnosed in a 53-year-old woman in December 2014. After chemotherapy, the disease was treated with autologous bone marrow transplantation in June 2015. Remission was observed through two months, but in August the patient was hospitalized due to severe headache with neck stiffness. Meningitis or viral encephalitis were suspected following her investigation. She was taken to the Intensive Care Unit because of a progression to status epilepticus. The EEG-examination revealed generalized slow wave activity and a right temporal epileptiform focus manifesting rarely. Clinical brain death developed on the 17th day in hospital. DISCUSSION - Although meningeal infiltration is infrequent in multiple myeloma, the present case report draws attention to this possibility. ]

[Carvedilol therapy in hypertension]

KÉKES Ede

[Author analyzed the properties and antihypertensive effect of one of the best beta blockers with vasodilative effects, the carvedilol on the base of the Hungarian and international literature . Author deals with this issue for many years and he presented his own experience. The beta blockers could never be missed on therapy of the endemic hypertension. They are equivalent to other drug family. This played a big role , that the new , strong beta-1 selective and -- especially 3. generation beta blockers (carvedilol and nebivolol) - came to the fore in the therapy of hypertension compared with conventional beta blockers. The carvedilol has many beneficial properties, as vasodilatation, antioxidant effect, beneficial effect on the vascular stiffness, regression of left ventricular hypertrophy, increasing coronary reserve. Carvedilol is able to stable success on the therapy of hypertension as monotherapy or combination with the other drugs. In Hungary the physicians applied beta blockers about 30-35% in the treatment of hypertension.]
